Description

DESCRIPCIÓNDESCRIPTION

Cabezal de bombeo y dispositivo dosificadorPump head and metering device

La presente invención se refiere a un cabezal de bombeo con una válvula elástica especialmente configurada que posibilita un cierre seguro del cabezal de bombeo. Mediante la válvula se garantiza que se garantiza un vaciado completo y, al mismo tiempo, cierre seguro del cabezal de bombeo, de modo que no queden restos del fluido a dosificar en el estado almacenado del cabezal de bombeo. Además, la presente invención se refiere a un dispositivo dosificador que puede estar configurado, por ejemplo, como una botella comprimible, como un sistema no sin aire o como un sistema sin aire, donde el dispositivo dosificador comprende un cabezal de bombeo según la invención.The present invention relates to a pump head with a specially configured elastic valve that enables a safe closing of the pump head. By means of the valve it is ensured that a complete emptying is guaranteed and, at the same time, a safe closure of the pumping head, so that there are no remains of the fluid to be dosed in the stored state of the pumping head. Furthermore, the present invention relates to a dosing device which can be configured, for example, as a squeeze bottle, as a non-airless system or as an airless system, where the dosing device comprises a pump head according to the invention.

Por el estado de la técnica se conocen sistemas de dosificación, como por ejemplo botellas comprimibles, sistemas no sin aire o sistemas sin aire. Estos sistemas se destacan por una dosificación en porciones del fluido a dispensar o por un dispensado continuo de fluido cuando se aplica una presión correspondiente al dispositivo dosificador. Sin embargo, como siempre no está resuelto el problema de que en la mayoría de los sistemas quedan restos de líquidos en el cabezal de bombeo una vez finalizado el proceso de dosificación. Esto es problemático en particular luego cuando el líquido restante puede representar un caldo de cultivo para bacterias o gérmenes, por ejemplo. En este caso se puede producir una contaminación de todo el contenido del sistema de dosificación, por lo que el contenido se vuelve inservible. Asimismo, es problemático si los residuos restantes de un líquido a dosificar, por ejemplo una solución, permanecen en el cabezal de bombeo y se secan allí. Entonces, los ingredientes disueltos pueden, por ejemplo, cristalizar, se puede producir un pegado o incrustación de las partes móviles del cabezal de bombeo, por lo que el sistema se vuelve inoperable.Dosing systems such as squeezable bottles, non-airless systems or airless systems are known from the state of the art. These systems are distinguished by a portioned dosing of the fluid to be dispensed or by a continuous dispensing of fluid when a corresponding pressure is applied to the dosing device. However, as always, the problem that in most systems remains of liquids remain in the pumping head once the dosing process has finished, has not been solved. This is particularly problematic later when the remaining liquid can represent a breeding ground for bacteria or germs, for example. In this case, contamination of the entire content of the dosing system can occur, so that the content becomes unusable. Likewise, it is problematic if residual residues of a liquid to be dosed, for example a solution, remain in the pump head and dry there. Then, the dissolved ingredients can, for example, crystallize, sticking or fouling of the moving parts of the pump head can occur, whereby the system becomes inoperable.

El documento EP 2130610 A1 describe un cabezal de bombeo con una válvula rígida según el estado de la técnica. Document EP 2130610 A1 describes a pump head with a rigid valve according to the state of the art.

Por tanto, el objetivo de la presente invención es especificar un cabezal de bombeo que no presenta las desventajas mencionadas anteriormente.Therefore, the object of the present invention is to specify a pump head that does not have the above mentioned disadvantages.

Este objetivo se logra con vistas a un cabezal de bombeo con las características de la reivindicación 1 y con vistas a un dispositivo dosificador con las características de la reivindicación 15. A este respecto, las respectivas reivindicaciones dependientes representan perfeccionamientos ventajosos.This object is achieved with a view to a pump head with the features of claim 1 and with a view to a metering device with the features of claim 15. In this respect, the respective dependent claims represent advantageous developments.

La presente invención se refiere, por tanto, a un cabezal de bombeo para un dispositivo dosificador para el dispensado dosificado de un fluido, que comprende una parte de cabezal con una abertura de salida para el fluido a dispensar, donde la parte de cabezal presenta una superficie interior, una válvula elástica, que en menos por zonas presenta una configuración geométrica correspondiente a la superficie interior de la parte de cabezal, un primer componente 40, que presenta una abertura de paso para el fluido a dispensar, a través de la que se posibilita una afluencia del fluido entre la parte de cabezal y la válvula elástica con la deformación de la válvula elástica configurando un espacio intermedio entre la válvula elástica y la parte de cabezal permite (estado de accionamiento (B)), donde la parte de cabezal y el primer componente 40 están conectados en arrastre de forma y de fuerza conectados con la inclusión de la junta de estanqueidad elástica entre la parte de cabezal y el primer componente 40, y la válvula elástica en un estado de almacenamiento (A) del cabezal de bombeo descansa en toda la superficie en arrastre de forma sobre la superficie interior de la parte de cabezal, de modo que se garantiza una estanqueidad por fluido entre la parte de cabezal y el primer componente 40.The present invention therefore relates to a pumping head for a metering device for metered dispensing of a fluid, comprising a head part with an outlet opening for the fluid to be dispensed, where the head part has a inner surface, an elastic valve, which in less than one area has a geometric configuration corresponding to the inner surface of the head part, a first component 40, which has a passage opening for the fluid to be dispensed, through which allows an influx of fluid between the head part and the elastic valve with the deformation of the elastic valve forming an intermediate space between the elastic valve and the head part allows (actuation state (B)), where the head part and the first component 40 are connected in form and force connection connected with the inclusion of the elastic sealing gasket between the head part and the pri mer component 40, and the elastic valve in a storage state (A) of the pumping head rests on the entire surface in form fit on the inner surface of the head part, so that fluid tightness between the head part and the first component 40.

Según la presente invención, la parte de cabezal y la válvula elástica están adaptadas entre sí. A este respecto, la válvula elástica descansa sobre la superficie interior de la parte de cabezal, de modo que se garantiza un cierre completo de la abertura de salida. Debido al hecho de que la válvula elástica está configurada de forma elástica al menos por zonas, la válvula elástica descansa en toda la superficie sobre la superficie interior de la parte de cabezal, de modo que en el estado de almacenamiento no queda espacio restante entre la parte de cabezal y la válvula elástica. Por tanto, todo el líquido a dosificar se dispensa desde el cabezal de bombeo a través de la abertura de salida al final del proceso de dosificación, es decir, cuando el cabezal de bombeo vuelve de un estado de accionamiento a un estado de almacenamiento.According to the present invention, the head part and the elastic valve are adapted to each other. In this connection, the elastic valve rests on the inner surface of the head part, so that a complete closure of the outlet opening is ensured. Due to the fact that the elastic valve is elastically configured at least in areas, the elastic valve rests over the entire surface on the inner surface of the head part, so that in the storage state there is no remaining space between the valve. head part and elastic valve. Thus, all the liquid to be dosed is dispensed from the pump head through the outlet opening at the end of the dosing process, ie when the pump head returns from an actuation state to a storage state.

A este respecto, la abertura de salida puede estar configurada de modo que el fluido se pueda dispensar en forma de gotas o en forma de niebla de pulverización por medio del cabezal de bombeo.In this connection, the outlet opening can be configured such that the fluid can be dispensed in the form of drops or in the form of spray mist by means of the pump head.

Una forma de realización preferida prevé que la válvula elástica comprenda una cabeza y una pared elástica, donde el cabezal presenta una configuración geométrica correspondiente a la superficie interior de la parte de cabezal y la pared elástica está configurada de forma deformable.A preferred embodiment provides that the elastic valve comprises a head and an elastic wall, where the head has a geometric configuration corresponding to the inner surface of the head part and the elastic wall is deformably configured.

Según esta forma de realización preferida, la pared de la válvula elástica está configurada en particular de forma elástica, mientras que el cabezal puede estar configurado de forma rígida y, por lo tanto, está adaptado directamente a la naturaleza de la superficie interior de la parte de cabezal. Por tanto, se garantiza un engranaje seguro del cabezal de la válvula elástica en la superficie interior de la parte de cabezal en la zona de la abertura de salida.According to this preferred embodiment, the elastic valve wall is designed in particular to be elastic, while the head can be designed to be rigid and is therefore directly adapted to the nature of the inner surface of the part. of header. Thus, secure engagement of the elastic valve head on the inner surface of the head part in the region of the outlet opening is ensured.

Se prefiere además en este caso que la pared elástica presente al menos un punto de doblez de consigna, en el que la pared elástica se dobla hacia dentro o hacia fuera cuando se transfiere del estado de almacenamiento (A) al estado de accionamiento (B).It is further preferred in this case that the elastic wall has at least one set point of bending, at which the elastic wall bends inwards or outwards when it is transferred from the storage state (A) to the storage state (A). drive (B).

La pared de la válvula elástica puede estar configurada, por ejemplo, en forma de un fuelle.

La presente invención se describe con más detalle con referencia a las figuras adjuntas, sin restringir la invención a las formas de realización específicamente representadas.The present invention is described in more detail with reference to the accompanying figures, without restricting the invention to the specifically shown embodiments.

La figura 1 muestra un cabezal de bombeo I que es adecuado en particular como cabezal dosificador para una botella comprimible. El cabezal de bombeo I comprende a este respecto una parte de cabezal 10 con una abertura de salida 11, que puede estar configurada preferiblemente para el dispensado de fluidos en forma de gotas. Sin embargo, asimismo es posible configurar la abertura de salida de modo que se pueda generar una niebla de pulverización al dispensar el fluido. A este respecto, la parte de cabezal 10 se asienta directamente sobre un componente 40 y está conectada en arrastre de forma y de fuerza a este. La parte de cabezal 10 presenta a este respecto una escotadura interior que presenta una superficie interior 12. Una válvula elástica 20, que presenta una cabeza 21a y una pared elástica 21b, está dispuesta entre la parte de cabezal 10 y el componente 40. La válvula 20 está representada en un estado de almacenamiento (A) y un estado de accionamiento (B). Se puede reconocer que en el estado de accionamiento (B) la pared elástica 21 b se dobla hacia dentro, para ello la pared elástica 21 b contiene preferiblemente un punto de doblez de consigna 24, que se puede ver en el estado de accionamiento (B). En el estado de almacenamiento (A), los puntos de doblez de consigna 24 están estirados de forma lisa. A este respecto, el cabezal 21 a de la válvula 20 puede estar configurado de forma maciza, la pared elástica 21 b puede estar unida al cabezal 21 a como una pared en forma de manga. La válvula completamente elástica 20 se puede fabricar en una pieza mediante el procedimiento de moldeo por inyección. Los elementos de fijación 23, por ejemplo un resorte circunferencial, están previstos en la pared elástica 21b. La válvula elástica 20 está fijada al cuerpo 40 mediante los elementos de fijación 23. Para ello, los elementos de fijación 23 se enclavan en los correspondientes elementos de fijación 43, por ejemplo una ranura circunferencial, del cuerpo 40. La superficie 22 del cabezal 21a de la válvula 20 presenta a este respecto una configuración idéntica a la superficie interior 12 de la parte de cabezal 10, de modo que el cabezal 21a de la válvula 20 en el estado de almacenamiento (A) puede engranar en arrastre de forma en la parte de cabezal 10 y por lo tanto cierra completamente la abertura de salida 11 De este modo, se cierra completamente el espacio intermedio 10-20 configurado en el estado de accionamiento (B) entre la parte de cabezal 10 y la válvula elástica 20, todo el fluido que está presente el estado de almacenamiento entre la parte de cabezal 10 y la válvula elástica 20 en el espacio intermedio 10-20 se descarga desde la abertura de salida 11 cuando el cabezal de bombeo se transfiere al estado de almacenamiento. El componente 40 presenta una pared 42 que separa constructivamente el cabezal de bombeo en una parte superior (la parte que comprende la parte de cabezal y la válvula elástica 20) y una parte inferior (por debajo de la pared 42). Un componente 60, que se puede conectar en arrastre de forma al componente 40, se inserta por debajo de la pared 42 del componente 40. Un espacio intermedio 40-60 resulta entre el componente 60 y el componente 40. A este respecto, el componente 40 presenta una abertura de paso 41 que, en el caso a modo de ejemplo, representado en la figura 1, está configurada de tal manera que en la parte inferior del componente 40 (a la altura del espacio intermedio 40-60) la abertura de paso 41 se pasa por la pared 44 del componente 40 y no se guía alrededor del componente 40 en una muesca (no mostrada) en la superficie exterior del componente 40. A este respecto, la muesca se comunica con un canal que conduce hacia arriba, representado a la izquierda en la figura 1, que desemboca en la otra abertura de paso 41 a través de la que el fluido se puede guiar en el espacio intermedio 10­ 20 entre la válvula 20 y la parte de cabezal 10. A este respecto, el canal guiado sobre la superficie del componente 40 se delimita y cierra por el componente 40 colocado.FIG. 1 shows a pump head I which is suitable in particular as a dosing head for a squeeze bottle. The pump head I here comprises a head part 10 with an outlet opening 11, which can preferably be configured for dispensing fluids in the form of drops. However, it is also possible to configure the outlet opening in such a way that a spray mist can be generated when dispensing the fluid. In this regard, the head part 10 sits directly on a component 40 and is positively and positively connected to it. In this case, the head part 10 has an inner recess which has an inner surface 12. An elastic valve 20, which has a head 21a and an elastic wall 21b, is arranged between the head part 10 and the component 40. The valve 20 is shown in a storage state (A) and a drive state (B). It can be seen that in the actuation state (B) the spring wall 21 b bends inwards, for this the spring wall 21 b preferably contains a setpoint bending point 24, which can be seen in the drive state (B). In the storage state (A), the set bend points 24 are smoothly stretched. In this connection, the head 21 a of the valve 20 can be solid, the elastic wall 21 b can be connected to the head 21 a as a sleeve-shaped wall. The fully elastic valve 20 can be manufactured in one piece by the injection molding process. Fixing elements 23, for example a circumferential spring, are provided on the elastic wall 21b. The elastic valve 20 is fixed to the body 40 by means of the fixing elements 23. To do this, the fixing elements 23 engage in the corresponding fixing elements 43, for example a circumferential groove, of the body 40. The surface 22 of the head 21a In this case, the valve head 20 has an identical configuration to the inner surface 12 of the head part 10, so that the head 21a of the valve 20 in the storage state (A) can positively engage in the head part. of head part 10 and thus completely closes the outlet opening 11. In this way, the intermediate space 10-20 configured in the actuation state (B) between the head part 10 and the elastic valve 20 is completely closed, the entire fluid that is present in the storage state between the head part 10 and the elastic valve 20 in the interspace 10-20 is discharged from the outlet opening 11 when the pump head is transferred to the storage state. The component 40 has a wall 42 constructively separating the pumping head into an upper part (the part comprising the head part and the elastic valve 20) and a lower part (below the wall 42). A component 60, which can be positively connected to the component 40, is inserted below the wall 42 of the component 40. An intermediate space 40-60 results between the component 60 and the component 40. In this regard, the component 40 has a passage opening 41 which, in the exemplary case shown in FIG. 1, is designed in such a way that in the lower part of the component 40 (at the height of the gap 40-60) the opening of passage 41 passes through wall 44 of component 40 and is guided around component 40 in a notch (not shown) in the outer surface of component 40. In this regard, the notch communicates with a channel leading upwards, shown on the left in FIG. 1, which empties into the other passage opening 41 through which the fluid can be guided into the intermediate space 10 between the valve 20 and the head part 10. In this connection, the guided channel on component surface 40 it is delimited and closed by the placed component 40 .

El componente 60 dispone de una pared 62 colocada en el lado del cabezal en la que está insertada una abertura de paso excéntrica 63. A este respecto, el componente 60 se enchufa en el componente 40 de tal manera que la pared 62 no termina directamente con la pared 42 del componente 40, sino que se conserva una zona intermedia 40-60 y, por lo tanto, la abertura de paso 41, que está dispuesta en la parte inferior del componente 40, permanece abierta. En el caso a modo de ejemplo del cabezal de bombeo I según la figura 1, entre el componente 40 y el componente 60 está colocado un material 50 que filtra bacterias, a través del que es posible un intercambio de aire entre la zona interior del cabezal de bombeo y el entorno. El componente 60 dispone de una escotadura 61 en la que está incorporado un pistón hueco 70 con un volumen hueco interior 71. A este respecto, el pistón hueco 70 está dispuesto en la escotadura 61 de forma móvil en la dirección axial (hacia arriba y hacia abajo en la figura 1). Además, el cabezal de bombeo puede disponer de un elemento de junta 80, a través del que es posible una colocación obturadora del cabezal de bombeo I sobre un recipiente de acopio II, no representado en la figura 1.The component 60 has a wall 62 arranged on the head side, in which an eccentric passage opening 63 is inserted. In this connection, the component 60 is plugged into the component 40 in such a way that the wall 62 does not end directly with the wall 42 of the component 40, but an intermediate zone 40-60 is preserved and therefore the passage opening 41, which is arranged in the lower part of the component 40, remains open. In the exemplary case of the pump head I according to FIG. 1, a bacteria-filtering material 50 is placed between component 40 and component 60, through which an exchange of air is possible between the inner area of the head pumping and the environment. The component 60 has a recess 61 in which a hollow piston 70 with an inner hollow volume 71 is incorporated. In this connection, the hollow piston 70 is arranged in the recess 61 to be movable in the axial direction (up and down). down in figure 1). In addition, the pump head can be provided with a sealing element 80, through which sealing placement of the pump head I on a storage container II, not shown in FIG. 1, is possible.

La figura 2 muestra un cabezal de bombeo I según la figura 1, que está representado en un recipiente de acopio II, en el caso de la figura 2 una botella comprimible. El recipiente de acopio II contiene a este respecto un fluido a dispensar, que está representado rayado en la figura 2a en el recipiente de acopio II. La figura 2a muestra una sección a través de la disposición general en el estado de uso, la figura 2b muestra el detalle del cabezal de bombeo I bordeado en la figura 2a. En este caso se han utilizado las mismas referencias que las representadas en la figura 1. En la figura 2b, con la flecha X, a través del paso 71 del pistón hueco 70, a través de la zona intermedia 40-60 entre el componente 60 y el componente 40, a través de la abertura de paso 41, a través del espacio intermedio 10-20, que se produce al accionar el dispositivo de medición según la figura 2, y finalmente en la dirección de la abertura de salida 11, se indica la ruta de acceso del fluido del contenedor de almacenamiento I en la dirección de la abertura de salida 11.FIG. 2 shows a pump head I according to FIG. 1, which is represented in a storage container II, in the case of FIG. 2 a squeeze bottle. In this case, the storage container II contains a fluid to be dispensed, which is shown hatched in FIG. 2a in the storage container II. Figure 2a shows a section through the general arrangement in the state of use, Figure 2b shows the detail of the pump head I bordered in Figure 2a. In this case the same references as those shown in Figure 1 have been used. In Figure 2b, with the arrow X, through the passage 71 of the hollow piston 70, through the intermediate zone 40-60 between the component 60 and the component 40, through the passage opening 41, through the interspace 10-20, which is produced by actuating the metering device according to figure 2, and finally in the direction of the outlet opening 11, is indicates the access path of the fluid from the storage container I in the direction of the outlet opening 11.

La figura 3 muestra el mismo dispositivo dosificador según la figura 2 cuando se aplica una presión (indicada por las flechas en la figura 3a) sobre la botella comprimible II. En este caso, el pistón hueco 70 (véase la figura 3b) se presiona hacia abajo (indicado por la flecha a la izquierda junto al pistón hueco 70) y por tanto el fluido situado por debajo del pistón hueco 70 y encerrado por el pistón hueco 70 y el componente 60 se presiona a través de la abertura de paso 43 del componente 60 en el espacio intermedio 40-60. Con la excepción de la referencia 70, no se han insertado otras referencias en la figura 3 por razones de claridad. El fluido 41 se presiona más en el espacio 10-20 entre la válvula elástica 20 y la parte de cabezal 10 del cabezal de bombeo I a través de la abertura de paso 41. En este caso tiene lugar una deformación de la válvula elástica que, como se muestra en la figura 3b, se dobla y libera así la abertura de salida 11, por lo que puede escapar el fluido. Debido al hecho de que a través del canal de paso 71 del pistón hueco 70 y la abertura de paso 63 del componente 60 no están dispuestos de forma congruente, cuando el pistón hueco 70 golpea la pared 62 del componente 60 tiene lugar un cierre la abertura de paso 63. Por lo tanto, incluso con una aplicación adicional de presión, no es posible una salida adicional de un fluido desde el dispositivo dosificador, ya que el canal de paso 63 está cerrado. Por tanto, con este cabezal de bombeo I es posible un dispensado dosificado de líquido desde una botella comprimible. El estado representado en la figura 3b corresponde al estado de accionamiento (B) del cabezal de bombeo.Figure 3 shows the same metering device according to Figure 2 when a pressure (indicated by the arrows in Figure 3a) is applied on the squeeze bottle II. In this case, the hollow piston 70 (see Figure 3b) is pressed downwards (indicated by the arrow on the left next to the hollow piston 70) and thus the fluid below the hollow piston 70 and enclosed by the hollow piston 70 and the component 60 is pressed through the passage opening 43 of the component 60 in the gap 40-60. With the exception of reference 70, no other references have been inserted in Figure 3 for the sake of clarity. The fluid 41 is further pressed into the space 10-20 between the elastic valve 20 and the head part 10 of the pump head I through the passage opening 41. In this case, a deformation of the elastic valve takes place, which, as shown in Fig. 3b, it bends and thus releases the outlet opening 11, whereby the fluid can escape. Due to the fact that through the passage channel 71 of the hollow piston 70 and the passage opening 63 of the component 60 are not arranged congruently, when the hollow piston 70 hits the wall 62 of the component 60 a closing of the opening takes place. passage 63. Therefore, even with a further application of pressure, a further outflow of a fluid from the dosing device is not possible, since the passage channel 63 is closed. Thus, with this pump head I a metered dispensing of liquid from a squeeze bottle is possible. The state represented in figure 3b corresponds to the actuation state (B) of the pumping head.

La figura 4 muestra una forma de realización en la que el dispositivo dosificador, en particular el cabezal de bombeo se transfiere del estado de accionamiento al estado de almacenamiento. En aras de la claridad, no están representadas las referencias, no obstante, son válidas las mismas afirmaciones que en las figuras anteriores. La figura 4a representa a este respecto un detalle ampliado del dispositivo dosificador representado en la figura 4b. Como se puede ver en la figura 4a, el pistón hueco 70 está como siempre en la posición final que se alcanza durante el proceso de accionamiento que se representa en la figura 3. Una vez finalizado el proceso de accionamiento, el usuario puede transferir el dispositivo dosificador a la posición de almacenamiento, donde el dispositivo dosificador, en el caso de la figura una botella comprimible, se pone sobre la cabeza. En este caso, el usuario suelta la botella comprimible, debido a la fuerza de recuperación de la botella comprimible, esta adopta de nuevo su forma original, como está representado en la figura 2. La fuerza de recuperación está representada en la figura 4b mediante las flechas que apuntan hacia afuera. Debido al volumen de líquido extraído se crea una depresión en el recipiente de acopio II durante este proceso, que continúa a través del pistón hueco 70 en el cabezal de bombeo I del dispositivo dosificador. Para compensar la presión se aspira aire en el recipiente de acopio 2 a través de un filtro estéril. En este proceso, el pistón hueco 70 también se mueve de vuelta a su posición inicial, es decir, en el caso representado en la figura 4, el pistón hueco 70 se mueve hacia abajo. Es posible una entrada de aire (flecha L) en el interior del recipiente de acopio II, es decir, la botella comprimible, a través del filtro de bacterias 50, que puede estar presente entre el componente 60 y el componente 40, por ejemplo.Figure 4 shows an embodiment in which the metering device, in particular the pump head, is transferred from the actuation state to the storage state. For the sake of clarity, they are not represented references, however, the same statements as in the previous figures are valid. FIG. 4a represents in this respect an enlarged detail of the metering device shown in FIG. 4b. As can be seen in figure 4a, the hollow piston 70 is as always in the final position that is reached during the actuation process which is represented in figure 3. Once the actuation process is finished, the user can transfer the device dispenser to the storage position, where the dispenser device, in the case of the figure a squeeze bottle, is placed on the head. In this case, the user releases the squeeze bottle, due to the restoring force of the squeeze bottle, it assumes its original shape again, as shown in figure 2. The restoring force is represented in figure 4b by the arrows pointing out. Due to the volume of liquid withdrawn, a depression is created in the collection container II during this process, which continues through the hollow piston 70 in the pump head I of the dosing device. To equalize the pressure, air is sucked into the storage container 2 through a sterile filter. In this process, the hollow piston 70 also moves back to its initial position, that is, in the case shown in Fig. 4, the hollow piston 70 moves downward. An inlet of air (arrow L) into the interior of the collection container II, i.e. the squeeze bottle, is possible through the bacteria filter 50, which may be present between component 60 and component 40, for example.

La figura 5 muestra la posición de almacenamiento (A) de la botella, en la que el pistón hueco 70 está representado en su posición final y la botella comprimible II está completamente relajada (véase la figura 5b).Figure 5 shows the storage position (A) of the bottle, in which the hollow piston 70 is shown in its final position and the squeeze bottle II is fully relaxed (see Figure 5b).

La figura 6 muestra otra forma de realización de un cabezal de bombeo según la invención, donde los componentes 10, 20, 30 y 40 están configurados de construcción esencialmente idéntica a los componentes correspondientes según la figura 1. A este respecto, las referencias correspondientes designan componentes idénticos. La diferencia esencial entre el cabezal de bombeo I según la figura 6 y el cabezal de bombeo I según la figura 1 es a este respecto que el cabezal de bombeo I según la figura 6 se puede accionar activamente, es decir, los componentes 40 y 60 no están conectados entre sí de forma fija, sino que están configurados de forma móvil uno respecto a otro a través de un elemento de resorte 55. Para realizar este movimiento, la parte de cabezal 10 comprende a este respecto adicionalmente un asa 13, a través de la que un usuario puede ejercer presión sobre la parte de cabezal y por tanto puede presionar los componentes 10 a 40 en la dirección del componente 60. A diferencia de la forma de realización según la figura 1, el componente 60 está configurado abierto a este respecto, es decir, no presenta una pared 62 que cierre hacia abajo. Un pistón hueco 70, que presenta un canal de paso 71, está guiado a través de la escotadura 61 del componente 60. El pistón hueco, por su parte, desemboca en una carcasa de bomba 100 que presenta un volumen de bombeo 101 y una abertura de entrada 102. Una válvula 90, por ejemplo una válvula de disco, está dispuesta en el lado de fondo en la abertura de entrada. La particularidad del cabezal de bombeo I según la figura 6 reside en el hecho de que los componentes 10, 40 y 60 en particular están obturados herméticamente entre sí, de modo que no es posible un intercambio de aire entre los volúmenes interiores del cabezal de bombeo I y el entorno. Por tanto, el cabezal de bombeo I según la figura 6 es un cabezal de bombeo sin aire.Figure 6 shows another embodiment of a pump head according to the invention, where the components 10, 20, 30 and 40 are configured in essentially identical construction to the corresponding components according to Figure 1. In this respect, corresponding references designate identical components. The essential difference between the pump head I according to FIG. 6 and the pump head I according to FIG. 1 is in this respect that the pump head I according to FIG. 6 can be actively driven, i.e. the components 40 and 60 they are not fixedly connected to each other, but are configured to be movable with respect to one another via a spring element 55. To carry out this movement, the head part 10 additionally comprises a handle 13, through from which a user can exert pressure on the head part and thus can press the components 10 to 40 in the direction of the component 60. Contrary to the embodiment according to FIG. 1, the component 60 is configured open to this respect, that is to say, it does not present a wall 62 that closes downwards. A hollow piston 70, which has a passage channel 71, is guided through the recess 61 of the component 60. The hollow piston, for its part, opens into a pump housing 100, which has a pump volume 101 and an opening inlet port 102. A valve 90, for example a disc valve, is arranged on the bottom side at the inlet opening. The particularity of the pump head I according to figure 6 lies in the fact that the components 10, 40 and 60 in particular are hermetically sealed with each other, so that an exchange of air between the internal volumes of the pump head is not possible. I and the environment. Therefore, the pump head I according to Fig. 6 is an airless pump head.

Durante este proceso de bombeo, la válvula 90 permanece cerrada, de modo que se produce una reducción del volumen de bombeo 101. El líquido situado en el volumen 101 se presiona de este modo hacia arriba a través del canal de paso 71 del pistón hueco 70 y, conforme a los principios ya explicados en la figura 1 se eyecta a través de la abertura de paso 41 del componente 40 y el espacio intermedio 10-20 que se configura entre la válvula 20 y la parte de cabezal 10 a través de la abertura de salida 11. En este caso, el recipiente de acopio II está configurado como un contenedor rígido, en el que, por ejemplo, también se puede utilizar un fuelle 200.If a user actuates the pump head I in a dosing device according to FIG. 7 via the handle 13, then the hollow piston 70 fixed relative to the component 40 is also pressed down into the pump housing 100 together with the pump part. head 10. During this pumping process, the valve 90 remains closed, so that a reduction of the pumping volume 101 takes place. The liquid located in the volume 101 is thus pressed upwards through the passage channel 71 of the hollow piston 70 and, according to the principles already explained in figure 1, it is ejected through the passage opening 41 of the component 40 and the intermediate space 10-20 that is configured between the valve 20 and the head part 10 through of the outlet opening 11. In this case, the storage container II is configured as a rigid container, in which, for example, a bellows 200 can also be used.
